Nitrate IonThorium Nitrate is a highly water soluble crystalline Thorium source for uses compatible with nitrates and lower (acidic) pH. All metallic nitrates are inorganic salts of a given metal cation and the nitrate anion. The nitrate anion is a univalent (-1 charge) polyatomic ion composed of a single nitrogen atom ionically bound to three oxygen atoms (Formula: NO3) for a total formula weight of 62.05. Nitrate compounds are generally soluble in water. Nitrate materials are also oxidizing agents. When mixed with hydrocarbons, nitrate compounds can form a flammable mixture. Nitrates are excellent precursors for production of ultra high purity compounds and certain catalyst and nanoscale (nanoparticles and nanopowders) materials. Thorium Nitrate is generally immediately available in most volumes. Ultra high purity, high purity, submicron and nanopowder forms may be considered. We also produce Thorium Nitrate Solution. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Thorium (Th) atomic and molecular weight, atomic number and elemental symbol Thorium (atomic symbol: Th, atomic number: 90) is a Block F, Group 3, Period 7 element with an atomic weight of 232.03806. The number of electrons in each of thorium's shells is [2, 8, 18, 32, 18, 10, 2] and its electron configuration is [Rn] 6d2 7s2. Thorium Bohr ModelThe thorium atom has a radius of 179 pm and a Van der Waals radius of 237 pm. Thorium was first discovered by Jöns Jakob Berzelius in 1829. The name Thorium originates from the Scandinavian god Thor, the Norse god of war and thunder.Elemental Thorium In its elemental form, thorium has a silvery, sometimes black-tarnished, appearance. It is found in small amounts in most rocks and soils. Thorium is a radioactive element that is currently the best contender for replacing uranium as nuclear fuel for nuclear reactors. It provides greater safety benefits, an absence of non-fertile isotopes, and it is both more available and abundant in the Earth's crust than uranium.
